Why do mallards sometimes nest far from water?
Mallards look for nesting locations away from likely predators. In urban environments this may include raccoons, coyotes, dogs and cats. Urban parks are typically over-populated with ducks and females may also look for nesting locations away from drakes (male ducks) that may attempt to copulate with them even after egg laying. It is not uncommon for ducks to nest as far as a mile from water.
